Abstract: A quick connect coupling incorporates several improvements including the combination of several functions into a single component. A single stop member provides a structure for holding a check valve spring, and also provides a stop for the check valve. The single component further provides positioning for an o-ring. The coupling also includes a pilot which includes compressible ribs at its outer peripheral surface such that the pilot is self-centering preventing excessive off-centering of the tube. In addition, the position of an o-ring relative to a retainer is tightly controlled such that upon insertion of a tube into the connector, the tube will initially encounter a resistance force by compression of the seal. Once this resistance force is overcome, the tube will immediately begin to encounter a resistance force from the retainer. Thus, an installer does not see two separate resistance forces, but rather sees a continuous single resistance force.
